FIGS. 16, l7, l8 and 19 are diagrammatic perspective views of several illustrative structural arrangements which may be assembled in accordance with the invention.

In FIG. I is shown a perspective view of one of the modular cubical blocks B in accordance with the invention, which preferably is molded of rigid plastic material, and is provided on the six faces thereof with annular projections for selective coupling thereto of cylindrical structural members or other types of connector elements.

In the preferred embodiment of the invention shown in FIGS. 1 to 3, the opposite faces 1 and 2 of the cubical block B are provided with resilient annular projections 11 and 12 extending, respectively, from faces 1 and 2 which may be molded integrally with the surfaces of the block. These projections are of plastic material such as polyethylene, and have sufficient flexibility to permit the passage of a bead at the end of a metallic cylindrical can so that the latter is detachably connected to the surface of the block and is retained in place by the flexible lip 11 and 12, respectively, which embraces the lateral wall of the can and retains the bead of the latter within a groove extending inwardly of the resilient lip.

Similar annular projections are provided on another pair of faces 3 and 4 of the cube and, as shown in FIG. 3, the annular projections 13 and 14 extend outwardly from these faces and terminate in the inwardly directed resilient lips 13 and 14, respectively, for engaging the ends of beaded cylindrical members which may be affixed thereto.

The last pair of faces 5 and 6 of the cube are constructed differently than the pairs of faces 1,2 and 3,4 described above. In the case of face 5 of the cube, the same is fitted with an annular projection 15 similar to annular projections II, 12, I3 and 14, described above, and is provided with an inwardly directed resilient lip 15 for embracing the end of a beaded can or other connector. However, face 6 of the cube is provided with a cylindrical projection 16 which is molded with an outwardly directed rib 16 of a dimension and contour of the same order as that of an annular bead at the end of the can so that this rib 16 may be coupled with annular projections provided with flexible lips of the type extending from the other faces of the cube or flexible lips on different types of connectors which are described in greater detail below.

Preferably, the plastic cylindrical projections 16, 16 may be of the same rigidity as the body of the cubical block while the annular projections on other faces of the block have flexible characteristics.

Annular connectors of plastic material such as polyethylene may be used to interconnect the cylindrical member together. and one embodiment of such is illustrated in FIGS. 4 to 6. A central web or diaphragm 20 serves to impart sufficient rigidity to the connector while the annular flanges extending from both sides thereof imparts resilience to the unit so that the inwardly directed lips 23 and 23 may flex sufficiently to embrace the lateral walls of the cylindrical cans immediately adjacent to the terminal beads 8 which are received in grooves 24, 24 adjacent to the central web 20.

A tab 25 extends outwardly from the periphery of the connector, and serves not only to facilitate the manipulation of the connector relative to the beads with which the same is engaged, but in addition serves as a spacer in the setup of the construction toys, as explained in greater detail below.

The structural element or connector shown in FIGS. 4 to 6 may have a length of approximately one-half inch, but connectors of different length may be provided and such a variant embodiment is illustrated in FIG. 7 where the connector C is of greater length and is formed of two spaced webs 30 and 30, wherefrom project the annular flanges 31,31 terminating in flexible lips 32,32 beyond grooves 33,33, respectively, which receive the beaded ends of the cylindrical cans.

Such connectors as shown in FIGS. 4 to 7 may be used alternatively or in conjunction with structural elements in the form of adapters as shown in FIGS. 8 to 10, the purpose of which is to effect connections between the cubes and/or cylindrical members when variations in length of the latter are encountered. The adapters A may be formed of resilient plastic material of the type of polyethylene and other such plastics, and are provided with a transverse circular web 40 therein to impart strength thereto. An annular flange 41 at one end of the adapter terminates in an inwardly directed flexible lip 42, for the purpose of embracing the lateral wall of a cylindrical member adjacent the bead thereof or an annular rib of another adapter. The opposite end of the adapter A is fitted with a cylindrical projection 43 which terminates in an outwardly extending rib 44 of the same dimension and contour as the annular bead on a cylindrical member so that this rib may be embraced by the flexible lip of any connector C which may be coupled therewith.

In FIG. 11 is shown one of the many countless ways in which the cubical blocks may be combined with the cylindrical structural members and the connectors and adapters in the construction of a desired structural unit. Thus, two cubical members may be connected detachably by coupling the annular projection 15 extending downwardly from the upper cubical block B with the cylindrical projection 16 extending from the upper face of the lower block B. A cylindrical can 10, of conventional length, is coupled detachably to the annular projection 13 extending laterally from the upper block, while a shorter can a is connected with the annular projection 11 extending laterally from the lower block. If the desired assembly requires an equalization between the cylindrical struc tural members, an adapter A is affixed to the right end of the structural member 10a leaving the annular rib 44 on the right thereof free for the engagement of a connector C as shown in FIGS. 4 to 6. Thereafter, another cylindrical structural member 1012 may have the beaded end thereof coupled to the opposite end of the connector C to equalize the length of structural member 10 with that of the composite length of structural members 10a and 10b. Connectors C may be affixed to the right ends of the structural members extending from both the upper and lower blocks B and B to which may be connected additional cylindrical structural members in any desired manner. Furthermore, as shown in FIG. 11, the flexible annular projection extending from the lower end of the cubical block B may have connected thereto any number of cylindrical members 10 coupled with the connectors C in any desired arrangement.

In FIG. 12 is shown in greater detail, and on an enlarged scale, the interengagement of the cylindrical projection 16 with the outwardly directed rib 16' on cubical block B with the annular projection 15 and the inwardly directed resilient lip 15, which makes possible the close juxtaposition of a pair of cubical blocks leaving free the remaining faces thereof for the detachable connection of the cylindrical structural members in any desired direction. The engagement between blocks B and B also permits a relative rotation between them around the axis common to projections 15 and 16.

FIG. 13 shows the juxtaposition of an adapter A with a connector C, as shown in elevation in FIG. 11. Thus, the resilient lip 42 of the adapter A is snapped over the right end of cylindrical member 10a so that the head 8 of the latter is received within the groove 42'. The opposite end of the adapter, with the annular flange 43 and the rib 44 is coupled to the left end of the cylindrical member 10b by the engagement of the resilient lip 23' over the flange 43 and rib 44, while the opposite flange 21 of the connector 21 engages the lateral wall of the structural member 10b and the bead 8 at the end of the latter by means of the annular resilient lip 23.

FIG. 14 is an enlarged view showing the operation of the simple connector C for the purpose of coupling the juxtaposed ends of the cylindrical member 10 with the beads 8 at said ends. The flexible lips 23 and 23 encompass the ends of the lateral walls of the cans beyond the beads 8 which are seated in the grooves 24,24.

FIG. 15 illustrates graphically the function performed by the tabs in addition to the facilitation of the manipulation of the connectors C in the course of engagement and disengagement of them with the ends of the cans. Thus, in some structural arrangements when a cubical block is set upon a surface S with the cylindrical projection 16 and the rib 16 at the free end thereof, the cubical block and the cylindrical member 10 extending therefrom would have a tendency to tilt by virtue of the higher level of the attachment of the cylindrical member relative to the free end thereof. Thus, the location of the tab 25 in the lowermost position, which is of the same height as the degree of protrusion of the cylindrical projection from the bottom surface of the cubical block, serves to level the cylindrical member relative to the supporting surface S. This results in more stable structures, particularly if the tabs 25 are oriented at all points where supports thereby are desired.

In FIGS. 16 to 19 are shown a few different structural arrangements of the many which are possible, by the selective combination of the modular cubical blocks with the cylindrical members which may be coupled together selectively by the resilient lips on the cubical blocks, connectors and adapters with the annular outwardly directed ribs projecting from at least one face of the cubical blocks, as well as the annular outwardly directed ribs on the adapters and the annular beads on the ends of the cylindrical members. The annular construction of the lips and ribs on the cubical blocks, connectors and adapters, when used in conjunction with the beaded ends of the cylindrical members adapted to be connected thereto, makes possible relative rotary movement between the several parts when such is desired.

Thus, FIG. 16 may be considered a simulation of a robot which, incidentally, maybe maintained in a level condition by the disposition of the levelling tabs 25 at the bottom of the end coupling elements, as shown on an enlarged scale in FIG. 15.

FIG. 17 illustrates a gabled roof construction simulating a church, and FIGS. 18 and 19 are simulative of a chair and table construction, respectively.

The possibilities of variation of the structural units are limitless and depend solely upon the imagination and skill of the children or adults using the assembly.

While the specific embodiments of the invention illustrated herein make possible the most universal and diversified assemblies, the objectives of the invention may be attained with modifications of the modular cubical block. Thus, cubical blocks having less than five annular projections extending from the faces thereof, or cylindrical projections with outwardly directed ribs extending from more than one face of the cube may be used.

While the invention has its maximum potential for utility and economy by the use of spent beverage cans, it is possible to use cylindrical members having beaded ends of metal or other material if such are desired and available.

The resilient flexible lips on the cubical 1 blocks may be fabricated of any desired thermoplastic materials in addition to polyethylene mentioned above as long as they exhibit similar properties of resilience and flexibility, for example, vinyl plastics and the like.
